Statistics of Fractionalized Excitations through Threshold Spectroscopy
Statistics of Fractionalized Excitations through Threshold Spectroscopy
We show that neutral anyonic excitations have a signature in spectroscopic measurements of materials: The low-energy onset of spectral functions near the threshold follows universal power laws with an exponent that depends only on the statistics of the anyons. This provides a route, using experimental techniques such as neutron scattering …
